Title: Folded antenna
Inventor: SAKANISHI SHOICHI
IPC: H01Q9/28
Filed: 1989-05-31
Abstract: PURPOSE:To obtain an antenna having an effective length in matching with a wavelength of a prescribed electromagnetic wave by folding a dipole antenna end. CONSTITUTION:The end of a dipole antenna 1 is folded and the effective antenna length of the folded antenna 1 is selected to be nearly 1/2 wavelength of a radiating electromagnetic wave. That is, when the dipole antenna 1 is folded, reflection is caused at the folded point and the reduction effect of the wavelength exists, then it is required to match the effective length of the antenna 1 with lambda/2 (lambda is the wavelength). The effective length of the dipole antenna 1 with respect to its total length l+2d is selected to be equal to lambda/2. Thus, antenna having the effective length in matching with the wavelength of a prescribed electromagnetic wave is obtained.

Title: Color cathode-ray tube
Inventor: NAKASE KIYOTAKA
IPC: H01J29/32
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To improve brightness of a screen, without deteriorating self-color tolerance and other colors tolerance in the case of mislanding on a fluorescent screen by disposing apertures and phosphor dots having hexagonal shape in the same direction. SOLUTION: When a condition such that apertures of a shadow mask is formed in hexagons, shapes of phosphor dots 21 and electron beam spots 5 formed on a fluorescent screen 4 are also formed in hexagonal shape similar to each other. For example, opposite side distances of the phosphor dots 21 and electron beam spots 5 are respectively set as (b)=100 μm, and (c)=140 μm. When the distance between each neighboring phosphor dot is the same pitch of 150 μm, and the self-color tolerance is 20 μm, and other color tolerance is a minimum distance (d)=30 μm. When the condition that numbers and pitches of apertures and phosphor dots 21 are set the same as the case of the regular hexagon shape and the shapes are formed in a hexagonal shape which is longer m a Y-axis direction, the other colors tolerance is unified in all directions, and thereby values of (d) and (e) are equalized.  Accordingly, a brightness is improved by reducing a ratio of a black matrix.

Title: Screen printing method
Inventor: OKA YOSHINORI
IPC: B41M1/12
Filed: 1984-07-05
Abstract: PURPOSE:To stabilize shape, facilitate fitting a plain gauze and eliminate the need for high technical skill, by using a metallic lath as a screen plain gauze. CONSTITUTION:The metallic lath is obtained by drawing and cutting a sheet such as a cold rolled steel sheet, a brass sheet, a copper sheet, a stainless steel sheet, an aluminum sheet and a nickel sheet into a rhombic or other mesh form by a special machine at normal temperature, preferably, by flattening by a press or the like. The thickness and mesh opening ratio of the lath can be appropriately selected in accordance with the objective printing. Although a screen obtained by fitting a plain gauze to a frame is ordinarily used, the fitting is not necessarily required in the case of using the metallic lath as the screen plain gauze, and a printing screen can be obtained simply by supporting both side ends in the expandable direction of the metallic lath by simple fasteners.

Inventor: YAMAGUCHI KAZUFUMI
IPC: H04N1/028
Filed: 1993-06-10
Abstract: PURPOSE:To enable high-speed readout for a row of photoelectric converting elements for an image sensor. CONSTITUTION:A photodiode 12 is formed between the source region of an FET 14 and an Si substrate. The base region of a bipolar transistor 13 using the Si substrate as a collector is connected to the drain region of the FET 14.
